When an impact occurs, material is excavated that rises up into the air and often settles back down around the new crater. This material is called “ejecta,” and sometimes it can more resistant to erosion than the surrounding terrain.
With classic bowl-shaped craters, we often do not see the ejecta blanket, but in this observation of Domoni Crater, we can easily see how distinct the ejecta is, which might possibly be related to particular topographic features here in the northern part of the crater.
Below is a flyover sequence made from our digital terrain models of the crater, produced by digital artist Seán Doran.
